Description

[0001] The utility model relates to a film processing equipment technical field especially relates to a film wrinkle's flattening subassembly. BACKGROUND

[0002] In the production and processing of film materials, the film is usually transmitted in a high-speed continuous manner in the equipment and wound into a roll. In order to ensure product quality, the film must be kept flat and uniform in tension during operation. However, due to the influence of working condition fluctuations, equipment disturbances or film factors, the film often appears tension fluctuations during transmission and winding, which leads to the deviation of the running path, and further causes quality problems such as wrinkles, folds, and irregular winding.

[0003] In the prior art, the guide roller structure is rigidly fixed. Since the fixed guide roller cannot be flexibly adjusted according to the dynamic changes of the film tension, when the film tension fluctuates or the lateral force is uneven, the film running angle is difficult to adaptively adjust, which is easy to form wrinkles or folding phenomenon on the roller surface, affecting the flatness of the final winding and the quality of the finished product. Especially in the working condition of frequent tension changes or high-speed operation, the fixed guide roller responds slowly and lacks adjustment ability, which makes the wrinkle problem more prominent, and even causes film damage or equipment downtime.

[0025] As shown in Figures 1 to 5 The present application embodiment provides a film wrinkle flattening assembly, which comprises a guide roller 100, including a rotating cylinder 101, a support rod 102, a first support frame 103, and an adjusting member 104. The first support frame 103 is arranged on both sides of the guide roller 100 and fixed to a rack. The two ends of the rotating cylinder 101 are supported between the two first support frames 103. The support rod 102 is fixedly arranged inside the rotating cylinder 101 along the axial direction of the rotating cylinder 101. The adjusting member 104 is arranged between the support rod 102 and the rotating cylinder 101. The adjusting member 104 includes an adjusting rod 104a, a rotating wheel 104b, and a compression spring 104c. The middle part of the adjusting rod 104a is rotationally connected to the support rod 102. The two ends of the adjusting rod 104a are respectively provided with the rotating wheel 104b. The rotating wheel 104b is in rolling contact with the inner circumferential surface of the rotating cylinder 101. The compression spring 104c is arranged on both sides between the adjusting rod 104a and the support rod 102, for applying the same elastic pre-tightening force to the adjusting rod 104a, so that the adjusting rod 104a can maintain balance.

[0026] During the operation of the film, when the tension changes, a lateral force is applied to the rotating cylinder 101, causing the rotating cylinder 101 to deflect slightly relative to the support rod 102, and driving the adjusting rod 104a to deflect around the support rod 102. Under the elastic action of the compression spring 104c, the adjusting member 104 self-adaptively adjusts the deflection angle of the rotating cylinder 101, so that the film adjusts the operation posture in response to the tension direction, effectively flattens the wrinkles, and maintains the tension stable. By arranging a sensor to measure the deflection angle of the adjusting rod 104a,

[0027] The winding roller 200 comprises a winding cylinder 201, a main shaft 202, a second support frame 203, a first electric push rod 204, and a deflection piece 205; the winding cylinder 201 is sleeved outside the main shaft 202, both ends of the main shaft 202 are installed between the second support frames 203 arranged on both sides of the winding roller 200; the first electric push rod 204 is installed on the second support frame 203; the deflection piece 205 comprises a sliding sleeve 205a and two second electric push rods 205b, the sliding sleeve 205a is sleeved at the end of the main shaft 202 and can slide along the main shaft 202; the two second electric push rods 205b are rotatably connected with the side surface of the sliding sleeve 205a through deflection through holes.

[0028] By arranging the sensor, the angle of deflection of the guide roller 100 can be measured; when the guide roller 100 is slightly deflected, the two second electric push rods 205b act respectively to drive the sliding sleeve 205a to deflect with the main shaft 202, so that the winding cylinder 201 is deflected by the same angle relative to the guide roller 100, and the axes of the two are kept parallel. Meanwhile, by the deflection angle and the distance between the guide roller 100 and the winding roller 200, the distance of the lateral movement required by the first electric push rod 204 is obtained, the first electric push rod 204 drives the winding cylinder 201 to move laterally along the main shaft 202, so that the film is flatly wound on the winding cylinder 201 in a nearly vertical state, and the synergistic effect of stable winding and wrinkle suppression is realized.

[0029] The side wall of the rotating cylinder 101 is provided with a baffle 205c, which is fixedly arranged on the inner side surface of the rotating cylinder 101 and located outside the rotating wheel 104b. The baffle 205c is used to limit the movement range of the rotating wheel 104b when the rotating cylinder 101 and the adjusting piece 104 are relatively deflected, so as to prevent the rotating wheel 104b from being separated from the inner wall of the rotating cylinder 101 in the rolling contact process, thereby avoiding the failure of the adjusting piece 104 or the misplacement of the rotating cylinder 101, and ensuring the structural stability and safety of the deflection adjustment process, especially in the working condition of frequent deflection caused by film tension fluctuation, effectively improving the working reliability of the device.

[0030] The outer side of the rotating wheel 104b is provided with a clamping protrusion 104d, and the inner surface of the rotating cylinder 101 is provided with a clamping groove 104e corresponding in position, and the clamping protrusion 104d and the clamping groove 104e are clamped and matched with each other. Through the above structure, the rotating wheel 104b can keep synchronous movement with the rotating cylinder 101 in the process of rotating with the adjusting rod 104a, effectively avoiding the sliding phenomenon caused by insufficient friction, thereby avoiding the quality problems such as wrinkle and folding of the film in operation, and improving the flattening effect and product stability.

[0031] The baffle 205c is of annular structure and is integrally formed with the rotating cylinder 101.

[0032] The clamping protrusions 104d are arc-shaped, and a plurality of clamping protrusions 104d are arranged along the circumference of the rotating wheel 104b.

[0033] Working principle: the film wrinkle flattening assembly provided by the utility model realizes self-adaptive response to the film tension change through the cooperative structure of the guide roller 100 and the winding roller 200 in the film conveying and winding process, and then flattens the wrinkle and keeps the stable winding state.

[0034] In the running process, the film is guided into the winding roller 200 through the guide roller 100. When the film tension fluctuates, an uneven lateral force is applied to the rotating cylinder 101 of the guide roller 100, so that the rotating cylinder 101 produces a slight deflection around the internally fixed support rod 102. The deflection causes the adjusting part 104 mounted on the support rod 102 to act, and the adjusting rod 104a rotates around the support rod 102, and the rotating wheels 104b arranged at both ends roll on the inner wall of the rotating cylinder 101, so as to adapt to the change of the deflection angle.

[0035] The compression spring 104c applies a symmetrical elastic force to both ends of the adjusting rod 104a, so as to ensure good resilience and self-balancing ability in the adjusting process. The clamping protrusions 104d on the rotating wheels 104b are clamped with the clamping grooves 104e on the inner wall of the rotating cylinder 101, so as to effectively prevent the adjusting part 104 from slipping during the deflection process, and improve the accuracy and reliability of the adjusting response. In order to avoid excessive movement or disengagement of the rotating wheels 104b during the deflection process, the inner wall of the rotating cylinder 101 is also provided with an annular baffle 205c, which limits the movement range of the rotating wheels 104b, so as to ensure the stability of the overall structure, and is especially suitable for the working condition that the tension fluctuates frequently.

[0036] After the guide roller 100 is deflected, the angle sensor arranged in the system monitors the deflection angle of the adjusting rod 104a in real time and feeds back to the control system. The control system controls the two second electric push rods 205b of the winding roller 200 to drive the deflection part 205 respectively, so that the sliding sleeve 205a is deflected synchronously with the main shaft 202, so as to ensure that the winding cylinder 201 is parallel to the axis of the guide roller 100, the film enters the winding cylinder 201 at the optimal angle all the time, and the winding deviation and wrinkle caused by the incidence angle error are effectively avoided.

[0037] In addition, based on the distance and deflection angle between the guide roller 100 and the winding roller 200, the control system calculates the required horizontal displacement of the first electric push rod 204, and drives the winding cylinder 201 to be accurately adjusted along the direction of the main shaft 202, so that the film is always wound and collected flatly in a vertical posture.
